Embodiment Construction

[0016] The working principle of the present invention is as follows: when the vehicle is braked, step on the foot brake pedal, the oil pressure enters the brake caliper cylinder from the master cylinder through the oil pipe, and pushes the piston to move outward, so that the brake block assembly clamps the brake disc , to generate clamping force, so as to achieve service braking. When the parking brake is applied, after the hand brake is pulled, the parking cable drives the parking pull arm to rotate. Since the parking shaft and the parking pull arm are riveted together, the parking shaft is also driven to rotate, and the parking shaft and the parking nut are both It is installed inside the anti-rotation bushing to allow the parking shaft to rotate. The boss on the outer circle of the anti-rotation bushing is fixed in the arc groove of the brake caliper cylinder and cannot rotate, and the parking nut is only embedded in the anti-rotation bushing. On the swivel bushing, the par...

Abstract

The invention relates to brake calipers with a parking braking mechanism. The brake calipers comprise a brake caliper cylindrical body, a piston assembly, a parking braking mechanism and a parking braking pulling arm which is connected with the parking braking mechanism, wherein the parking braking mechanism comprises a parking shaft, a steel ball, an anti-rotating lining and a parking nut, an arc-shaped groove is arranged on a circumference of the inner wall of the brake caliper cylindrical body, an arc-shaped protrusion is arranged on a circumference of the outer wall of the anti-rotating lining, the arc-shaped protrusion is embedded in the arc-shaped groove, so that the anti-rotating lining can not rotate relative to the brake caliper cylindrical body, but the anti-rotating lining can move downward along a shaft of the brake caliper cylindrical body, the anti-rotating mechanism is not embedded from the outside of the brake caliper cylindrical body and works inside the cylindrical body, no impact force of external force is provided, no leakage risk exists, the safety factor is high, and the performance is reliable. Beside the product structure of the brake calipers is impact.

Description

technical field [0001] The invention relates to a brake caliper for automobile braking, in particular to an integrated brake caliper with the functions of parking brake and service brake. Background technique [0002] At present, the existing brake caliper assembly is composed of brake caliper cylinder, piston, piston sealing ring and brake block assembly, etc., which acts as a service brake; when applied to the rear wheels, due to the lack of parking mechanism, so it must be used in conjunction with an additional mechanism to realize the parking function. [0003] For the parking function to be implemented in the caliper, the interior of the caliper needs to include a parking mechanism that is actuated by the handbrake cable. [0004] For the above-mentioned brake caliper with a parking mechanism, a known case, such as a disc brake cylinder with a parking mechanism disclosed in Chinese patent CN: 01805802.7, in this mechanism, the hand brake cable pulls The rotating arm r...
